Hallin Marine awarded subsea construction project

July 23, 2013

Hallin Marine, a Superior Energy Services company, announced the receipt of a project off the northwest coast of Java. It centers on the installation of new control taps and a bypass for the main pipeline, which supplies 60% of Jakarta's gas requirements, to the mainland. Hallin will provide full saturation-diving services using the Ullswater subsea operations vessel. The Ullswater will be equipped with a remotely operated submersible vehicle that will be used for underwater observation and process monitoring.

Also on site from the Hallin fleet will be the Carlisle which was recently mobilized for duty as a diving support vessel. The Carlisle has a Hallin-designed-and-built modular SAT system permanently mounted on deck. This is augmented by DP2, 126-crew accommodation and a four-point mooring system.

Hallin teams based on the two vessels will be performing concrete coating removal on existing pipelines, pipeline integrity checks, spools installation, pre-commissioning assistance, installation of hot-taps at multiple locations, and the fitting of underwater pipe-closure stopples.

"Hallin won the contract on the basis of its successful track record as an experienced offshore-support-service provider and the company's knowledge in managing this type of project scope in the region," says John Payne, Hallin’s Chief Executive Officer. "Past Hallin operations have included riser installations in the Jangkar field, installation of rigid risers and flexible flowlines in the Belanak field, and installation of subsea umbilicals in the Natuna gas field."
